In this world, media have taken over our lives. People tend to believe everything that they see on social media. Scientists believe there are ways people can strengthen their brains. The science article is called Exercise, cognition, and the aging, brain; by Arthur F. Kramer, Kirk I. Erickson and Stanley J. Colcombe. The media article is called Can You Build a Better Brain? It was written by Sharon Begley and Ian Yarett. The media article does not do a good job of evaluating the important scientific information; the media article never mentions a majority of what it should have. This paper will show the public that there might be some things that the media articles are not telling us.

“Alzheimer’s disease was significantly higher for individuals who exercised fewer than three times per week (19.7 per 1,000 person yr) compared with those who exercised more than three times per week (13.0 per 1,000 person yr). A gene implicated in cognitive deficits and Alzheimer’s dementia, moderates the effects of fitness training on cognition” (Kramer). Some of the results that the scientists got were unclear. The media article did mention dementia. In Can You Build a Better Brain, they talk about how smoking can also increase your risk of dementia. “Cigarettes may boost your memory and attention,” (Begley) but in the future you may begin to see your teeth start turning yellow. Your skin not looking like how it should and your future might hold lung cancer and heart disease. In the Exercise, cognition, and the aging, brain article, researches have found that the participants who scored the lowest physical performance on the tests, will have more of a risk of seeing signs for having Alzheimer’s in the future. Just by doing some sort of exercise at least three times a week, the risk of you getting Alzheimer’s will decrease. You will also be less likely to get other types of diseases, such as heart disease which can led to a heart attack. Also by exercising daily, it can help strengthen your …show more content…
In a psychological state, it is known to affect the processes that control movement, emotional response, the ability to experience pleasure and pain. Nicotine has positive effects on motor skills, short-term memory, attention, and other cognitive skills. It also mentions two limitations: “you can get the same dopamine boosting benefits of the drug by simply believing that you’ll do well, which itself releases dopamine” (Begley). Our bodies already release a certain amount of dopamine when needed. If peoples’ bodies start to go off that trend, then bad things could happen. In the science article they provide an abundance of research, and ratios. The media article is misleading in this way. The difference of these two articles are the vocabulary and literacy, and the studies that they include. As addressed earlier, the science article went into detail about the research, the experiments conducted, and what they had found out. In the end the media article did not do a good job at explaining the science article.
The article was written based on a study conducted by Smith J., et al. The article describes how the hippocampus deterioration leads to Alzheimer’s – the disease usually targets the memory of the individual, a function of the hippocampus. Physical activity has been shown to preserve the hippocampus, therefore preserving the memory of the individual. If individuals at high risk of developing Alzheimer’s (individuals that carry the genetic marker, ApoE4, for Alzheimer’s) participate in physical exercise, they can lower their risk of developing the disease. Additionally, the article provided viewers with the information about the sample, method and the results. There were 4 groups of participants who were older adults with normal cognitive functioning, aged 65-89. The groups were classified by low/high Alzheimer’s risk and low/high physical activity rates. The sample’s hippocampus and physical activity levels were tracked over the course of 18 months. Furthermore, Science Daily provided an interview with one of the authors, Smith J. and a professor at University of Pittsburgh. The interviews gave insight into the mind of the author, lending a better perspective on the article and providing direct information to
Once people start smoking they can become addicted because of the nicotine in the cigarettes causing you to smoke more, than in the long term it causing cancer. Nicotine has a big effect in the brain and body causing disliked changes in behaviour making you depressed or drowsy. It will also create a physical dependency that will cause unpleasant symptoms.
In the world today, Nicotine is one of the most frequently used addictive drugs. The impact it has on society is like no other. It is one of more than 4,000 chemicals found in the smoke of tobacco products such as cigarettes, cigars, and pipes. This addictive drug is the primary component in tobacco that acts on the brain.
Research has proven that physical activity improves cognitive function and can also improve brain function throughout a lifespan. Moreover, staying physically active has so many benefits as well. For example, doing exercise and fitness activities help build cells and natural pathways to help reduce changes in memory loss or dementia. Also, it has so many health benefits including long-term improvements to the cognitive function as the young adult reaching mid
Cavanaugh and Blanchard-Fields (2015) state that there is research showing how brain plasticity can be enhanced through aerobic exercise (p.51). It is important that adults be active in their lives. A 30-minute walk or some type of physical activity will benefit them as the age. The text mentions a study done by Erickson and his colleagues in 2009 where they studied the effect of aerobic exercise on the hippocampus. They found that due to aerobic exercise it produced greater volume in the hippocampus. This is significant because the hippocampus is the part of the brain that is responsible for memory, emotions, and spatial functioning. The body does not only need physical activities to produce healthier cognitive functioning but also nutrients. The text identifies three nutrient biomarker patterns that are significant on the aging brain. These nutrients are vitamin B, C,D, and E, omega-3, and trans fat. the foods that belong to these nutrients are beneficial to the brain. Older adults should make an effort to include these nutrients into their diets. positive impacts these nutrients make are better cognitive functioning and greater brain
As reported by Heather’s, Nicotine contains a large amount of toxic substance which can lead to several causes and effects to health. The substances in nicotine effects on the brain and its addicted. When a person smokes, the nicotine substance travels to the brain within 10 seconds and changes the function of the brain. “Blood that enters the lungs to picks up oxygen also pickup something else – the nicotine”. It also rises the blood pressure by five to ten points and heart rate by ten to twenty beats per minute. However, nicotine also performs as a sense of feeling of pleasure. Nicotine reaches to brain within a speedy rate and disperses soon conversely, its increases use of cigarettes.
In the book Spark, written by Dr. John J. Ratey, he discusses how exercise can positively affect how your brain works. He provides studies and personal experiences to support the claims he makes. I always knew exercise would improve your life but never could have imagined how much it can affect your brain health as well. The chapter I thought spoke the most to me was chapter two, Learning: Grow Your Brain Cells.

Within Boost Your Brain, Dr. Fotuhi enlightens and coaxes the audience with a professional tone to complete his program by incorporating real-life scenarios along with proven facts to meet the needs
This article is about the prevention of the Alzheimer’s risk. Alzheimer disease is also called senile dementia. It is a disease where people lost their memories. This research was done at UCLA Medical Center and University of Pittsburgh. The researchers gathered the participants to do experiment on whether the physical activities benefits to reduce the Alzheimer’s risk. According to the article, the outcome of the experiment showed that increase in physical activities related with larger brain volumes. “Individuals experiencing this brain benefit from increasing their physical activity experienced a 50% reduction in their risk of Alzheimer's dementia.” The researchers actually prove that if you increase your physical activity, then there is
Similarly, however, the brain benefits from lifting weights in general. In “Lifting Weights, Twice a Week, May Aid the Brain,” an article discussing the relativity of weight lifting on the brain, Gretchen Reynolds suggests that resistance training is important to delaying the vulnerability of the brain with time. Reynolds reviews statistics that support exercise in slowing the process of lesions in the brain of white matter (which is the material that connects and passes messages between different brain regions). Because time ultimately catches up with us, Reynolds contemplates the effect that lifting weights has on the brain, as it does the muscles of the body, in order to demonstrate that importance of maintaining a healthy lifestyle. The article says that “a minimum threshold of exercise needs to be achieved” as a way to gain the attention of the older
Due to the inconsistency between studies there is no definitive exercise dosage or type that can aid in protection against dementia. However, from the evidence provided it suggests that higher levels of exercise can be used as a neuroprotective mechanism to prevent the onset of
In the past decade there has been increasing empirical research that examine cognitive training and the connection it has to stave off or slow the progression of dementia. Dementia is considered a progressive neurodegenerative disorder, which influences neural pruning within the brain structures of elderly individuals, leading to the decrease of cognitive abilities (Alzheimer´s Association Report, 2013); the onset of dementia can occur years before the diagnosis, therefore significant damage can have already occurred within the brain neural pathways (Blennow et al, 2006). Early prevention and reducing further progression of neural degeneration; involves the intervention of cognitive training and mental exercises; which can inhibit neuropathological
Nicotine not only affects the brain but it affects the user’s whole body. Nicotine makes the heart work harder to pump blood this extra stress on the heart can lead to high blood pressure, heart attack and stroke. Smoking can damage the lungs by blocking the airways and can lead to lung cancer and other repository diseases. Smoking not only harms the inside of your body but also damages your skin causing wrinkles, it
Nicotine affects nearly all components of the endocrine and neuroendocrine systems, including catecholamines, serotonin, corticosteroids and pituitary hormones.
The articles by Erikson et al., Gatz, Korol et al., and Draganski et al. explore the concept of increased physical activity and/or mental activity having effects on the cognitive function and development or deterioration of the brain as we age. Although I agree that physical exercise is critical in increasing cognitive function because of the health benefits it provides, as well as the increased blood flow and circulation throughout the body, I ultimately believe that a healthy brain is not achieved solely by physical exercise or mental exercise, but both. I think there is a link between physical and mental exercise, and that the combination of these two activities creates higher cognitive functioning of the mind as well as the body. The mind and body come together and meet to make an overall healthy individual.
